Description

YesWiki before 4.6.7 contains a second-order SQL injection vulnerability in AclService::updateRequestWithACL, where a stored username is concatenated unescaped into a read-ACL LIKE clause. Attackers can self-register an account name containing a double-quote payload, then load non-admin ACL-filtered listings to read database contents and bypass read ACLs.

CWE-89

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
